ROI BERT REINER, OF NEW JERSEY.

SHUTTLE.

Specification of Letters Patent.

Patented July 5,1921.

Application filed November 8, 1920. Serial No. 422,466.

To all whom it may concern:

Be it known that I, Ronnn'r REINER, citizen of the United States of America, residing at VVeehawken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Shuttles, of which the following is a speci fication.

The present invention relates to shuttles for embroidery machines particularly such in which the cover is held in closed position by friction.

With shuttles of this type as hitherto constructed, there is the drawback that the cover while being closed is liable when handled roughly or by unskilled hands to be depressed too far into the shuttle, thereby flat-- tening the delicate bobbin and upsetting the bobbin thread, resulting in the formation of knots and the consequent tearing of the threads during the operation, which results naturally are very objectionable.

The object of my invention is to obviate this drawback by simple means which, as far as I am aware, have never been employed with shuttles.

My invention substantially consists in the novel construction, arrangement and combination of parts as will be hereinafter more fully described and defined in the appended claims.

In the accompan ing drawings in which similar reference 0 aracters denote similar parts, Figure 1 is a bottom perspective view of my improved shuttle; Fig. 2 is bottom plan view of the shuttle, a part of which is shown in section, and, Fig. 3 is a cross section on line 33 of Fig. 2.

a denotes the shuttle, and b the cover which, as usual, is hinged at 0 to the rear end of the shuttle, and is so disposed relative to the mouth a of the latter, that when closed one side 6' thereof at its front part will frictionally engage the inner face of the wall a of the shuttle, while the opposite side 6 thereof will be free or out of contact with the wall a of the shuttle. This arrangement of a one sided frictional engagement between the cover and the shuttle 1s necessary, to facilitate the opening of the" cover. Owing to a slight resiliency inherent in the cover or hinge 0 thereof, the cover can be pressed laterally to release it from its frictional engagement.

sided support or stop is insufficient to prevent a further depression of the cover because the cover after ashort use slackens on its hinge and begins to-wabble, so that b an lncreased force it is caused to Slip 0 of the shoulder 6. This has been a long felt evil but owing to the fact that the shuttie and the space containing the bobbin are limited in size and shape, the solution of the problem has been met with great difiiculties.

I have solved this problem by providing in the outer face of the wall a of the shuttle adjoining the free edge 6 of the cover an impression f the bottom 9 of which projects into the interior of the shuttle only an exceedingly-short distance. This impression is located at a point where the cover, when pressed sidewise to release it, comes closest to the adjacent wall a of the shuttle so that its free edge 6 will engage the inwardly protruding wall 9 of said impression. Thus the protuberance 9 can be made of the smallest possible size.

Furthermore by locating the impression or stop at the front end or near the point of the shuttle its presence will not interfere with the bobbin nor thread.

' The manipulation of the shuttle will illustrate the advantage of my improvement.

When the bobbin is placed into the shuttle, the cover is depressed into closed dposition, causing it to snap into the notch and rest on the shoulder 6. When accidentall the cover in closing is pressed with suc force that it will have the tendency to slip off the shoulder e the latter will cause it to swing toward the opposite side of the shuttle and to engage with its edge 6 the pro- .trubera'nce g, which will prevent it from being depressed too far into the shuttle and to d'arna e the bobbin.
